Parameter Comparison

Engineering Selection Recommendations

Primary Selection (MSART042SCG1R2AWRA01): The MSART042SCG1R2AWRA01 is the recommended primary component for new designs. It maintains Active product status, ensuring long-term availability and manufacturer support. This part is supplied in standard Tape & Reel packaging suitable for automated assembly processes.

Secondary Selection (CQ0100ARNPO8BN1R2): The CQ0100ARNPO8BN1R2 manufactured by YAGEO is a qualified substitute with Active product status. This part offers the highest current inventory level (12930 pieces) and is supplied in Tape & Reel packaging. It is suitable for both new designs and production applications requiring high-volume sourcing.

Tertiary Selection (TMK042CG1R2AD-W): The TMK042CG1R2AD-W is a Taiyo Yuden alternative supplied in Cut Tape packaging. This part carries "Not For New Designs" status, indicating it is in the mature or declining phase of its product lifecycle. It is suitable for legacy design support and maintenance applications only. The Cut Tape packaging format may require manual handling or specialized equipment for assembly operations.

All three parts satisfy identical electrical specifications, mechanical dimensions, and compliance requirements. Selection between them should be based on product lifecycle status, packaging format compatibility with assembly processes, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TMK042CG1R2AD-W be used as a direct replacement for MSART042SCG1R2AWRA01?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical capacitance (1.2 pF), tolerance (±0.05 pF), voltage rating (25V), temperature coefficient (C0G/NP0), and package dimensions (01005/0402 Metric). The primary difference is packaging format: TMK042CG1R2AD-W is supplied in Cut Tape (CT) while MSART042SCG1R2AWRA01 is supplied in Tape & Reel (TR). Additionally, TMK042CG1R2AD-W carries "Not For New Designs" status, making it unsuitable for new product development.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on individual tape segments, typically requiring manual handling or specialized equipment. Both formats contain the same component and are electrically identical.

Q: Are all three substitute parts RoHS3 compliant?

A: Yes. MSART042SCG1R2AWRA01, TMK042CG1R2AD-W, and CQ0100ARNPO8BN1R2 are all ROHS3 Compliant, meeting environmental and hazardous substance restrictions.

Q: What does "Not For New Designs" mean for TMK042CG1R2AD-W?

A: "Not For New Designs" indicates the part is in the mature or end-of-life phase of its product lifecycle. While the part remains functional and available, the manufacturer does not recommend its use in new product designs. It is suitable for legacy system support, maintenance, and repair applications only.

Q: Can CQ0100ARNPO8BN1R2 be used in new designs?

A: Yes. CQ0100ARNPO8BN1R2 carries Active product status and is suitable for new designs. It is manufactured by YAGEO and maintains all required electrical specifications and compliance certifications.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. This simplifies inventory management and reduces storage costs compared to higher MSL-rated components.

Q: Are there any differences in the High Q feature listed for CQ0100ARNPO8BN1R2?

A: CQ0100ARNPO8BN1R2 is specified with a High Q feature. This indicates superior quality factor characteristics. However, this feature does not affect substitutability for applications requiring standard 1.2 pF, 25V, C0G/NP0 ceramic capacitors. The High Q characteristic provides additional performance margin in RF and precision analog applications.
